Sulfurous acid is commonly known to not exist in its free state, and due to this, it is stated in textbooks that it cannot be isolated in the water-free form. [4] However, the molecule has been detected in the gas phase in 1988 by the dissociative ionization of diethyl sulfite. [5]

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Attempted isolation of the common salts of bisulfite results in dehydration of the anion with formation of metabisulfite (S 2 O 2− 5), also known as disulfite: 2 HSO − 3 ⇌ S 2 O 2− 5 + H 2 O. Because of this equilibrium, anhydrous sodium and potassium salts of bisulfite cannot be obtained.
Sulfur oxoacids are chemical compounds that contain sulfur, oxygen, and hydrogen.The best known and most important industrially used is sulfuric acid.Sulfur has several oxoacids; however, some of these are known only from their salts (these are shown in italics in the table below).
The sulfoxylate anion (SO 2− 2) The thiosulfate anion (S 2 O 2− 3) Sodium thiosulfate, a salt containing the thiosulfate anion; S 2 O 2− 2, a reported sulfur oxyanion. However salts containing S 2 O 2− 2 and HS 2 O − 2 are not well characterized; they would be conjugate bases derived from the parent thiosulfurous acid (H 2 S 2 O 2 ...
These are mixed anion compounds, meaning the compounds are cations that contain one or more anions. Some have third anions. Some have third anions. Environmentally, tellurite [TeO 3 ] 2- is the more abundant anion due to tellurate's [TeO 4 ] 2- low solubility limiting its concentration in biospheric waters.
Some examples of antimonates and their structures are shown below: Li 3 SbO 4 has a NaCl superstructure with isolated Sb 4 O 12− 16 units. [3]Sodium antimonate, NaSbO 3, has the ilmenite structure, with hexagonal close packed oxide ions with each ion, Na + and Sb 5+ occupying a third of the octahedral sites.
